The given pie chart shows the marks obtained in an examination by a student (in degrees). Observe the pie chart and answer the question that follows.
If the total marks are 720, then what is the difference between the total marks obtained in Physics, Maths and Physical Education and the total marks obtained in Chemistry, Biology and English together?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e 80
| Understanding/Application |
|
Total marks = 720 Total marks scored in Physics, Maths and Physical Education = [(70 + 80 + 50) × 720]/360 = 400 Total marks scored in Chemistry, Biology and English = [(45 + 55 + 60) × 720]/360 = 320 |
| Difference = 400 - 320 = 80 |
